Foreword The MF-IDUCTOR is suitable for the inductive heating of
ferromagnetic components such as bearing rings, housings,
nuts, bolts and pipes. Depending on the workpiece, either
fixed or flexible inductors can be used. This makes the
MF-IDUCTOR a versatile tool for assembly, disassembly
or preheating. The PAD-inductor can be used to remove
stickers, layers of paint or paint residues on steel parts.
When disassembling shrink connections, the MF-IDUCTOR
specifically heats the component to be removed from the
outside, such as a bearing inner ring on the shaft. The bearing
inner ring expands due to the rapid heating and can therefore
be easily pulled o the shaft. The MF-IDUCTOR is also suitable
for loosening rusted screw connections or glued connections.

The pictograms appearing on the MF-IDUCTOR have the
following meanings:
Forbidden for persons with pacemaker or
other sensitive implants.
Caution! This equipment generates a magnetic
field which can erase magnetic data from
credit cards and the like.
Caution! This equipment includes components
which may reach high temperatures.
2. Safety, warnings and potential hazards
2.1 Explanation of the
pictograms
2.2 Description of
potential hazards The MF-IDUCTOR must not be used by persons
in the following groups:
■users with a pacemaker;
■users with psychiatric or physical
impairments whose use of the equipment
would present a hazard to the user or their
environment;
■users below 16 years of age without the
supervision of an adult.
■The user must carefully read this manual and be familiar
with the safety standards in the work practice.
■Follow the instructions in the manual at all times.
The following must be checked before the equipment is
connected to the mains supply:
■The original mains lead with its IEC Lock is connected (in
case of doubt, contact the supplier)
■The MF-IDUCTOR is undamaged (no cracks or holes in the
housing);
■Only use original MF-IDUCTOR inductors. Do not modify the
generator.
2.3 Safety measures
to be taken

Schaeer Technologies 9
The MF-IDUCTOR has a number of (patented) internal safety
features. If one of these trips the unit will switch o and
the LED will flash when the on/o button is depressed. The
MF-IDUCTOR is equipped with a patented microprocessor
induction generator. In the event of overloading or overheating
of the generator the processor automatically reduces the
power to prevent damage to the induction generator.
2.4 Error messages
2.5 Overheating protection The unit will stop heating whenever its internal temperature
rises too high. Check:
1. that the fan is still operating
2. that the ventilation holes are unblocked
3. that power is connected, to ensure cooling
4. that only inductors approved by the manufacturer are
being used.
Solution: Delay heating until the unit has cooled suciently.
The unit monitors the temperature itself, and it will not be
usable until the internal temperature has fallen suciently.
This will be detectable as you will hear the fan switch o.
2.6 Connection safety feature Check:
1. that the inductor is correctly connected
2. that the inductors are not damaged
3. that the inductors are not causing a short-circuit to earth
or between the inductors
2.7 Mains current protection Ensure that the power supply meets the requirements of the
respective MF-IDUCTOR version. See also chapter 6.
2.8 Voltage and current
protection
Check:
1. that the mains voltage is not too high
2. that the inductor is not causing a short-circuit to earth,
or internally
3. where the flexible inductor is being used, that not too
many turns have been wound around the object to be
heated.
Solution: Remove some turns from the object to be heated and
retry.

3.1 Application The MF-IDUCTOR is a power tool that uses mid frequency
induction technology for heating ferromagnetic metals e.g.:
screws, tubes, bushings or bearing inner rings. Depending on
the application, dierent flexible inductors, fixed inductors
and a PAD-inductor are available, see point 6.3 Accessories.
Due to the wide variety of plug types, the power cable supplied
may not fit the wall socket. In such cases, obtain a power cable
with an IEC C13 connector and a mains plug that fits.
3.3 Plug types
IEC C13 connector CEE 7/7 (CE)
Nema 5-15 (USA / Canada) BS 1363 (UKCA)

Schaeer Technologies 11
A fixed or flexible inductor must be connected to the unit.
This connection is extremely robust, thanks to the patented
clamping mechanism. Fixed and flexible inductors are
connected or removed by simultaneously depressing both
buttons on the side of the unit.
The inductors contact points are then fully inserted in the
holes at the front of the MF-IDUCTOR. The buttons should then
be released. The patented clamping mechanism will ensure
that the inductor is held very firmly in place. Before using the
unit check that the contacts have been fully inserted and that
the connection is tight.
WARNING!
Select a fixed inductor which will fit closely
around the object to be heated without
touching it. This allows the optimal transfer
of magnetic energy so that the object heats
up as fast as possible, as well as preventing
the inductors protective sleeve from being
damaged by contact or wearing faster due to
overheating.
4. Operation
4.1 Connecting inductors

12 Schaeer Technologies
WARNING!
When using the flexible induction inductor and
U-inductor it is important to wind as few turns
around the object as possible. Where excessive
turns are wound the current amperage will
rise too high and the safety cut-out will trip.
The optimal number of turns will vary between
objects. Start with a single turn and gradually
increase the number of turns as necessary.
WARNING!
If the MF-IDUCTOR is used in one of the lower
power settings it may produce a ticking sound:
this is normal and not a fault.

Schaeer Technologies 13
4.2 Rotary switch and
push button
The patented rotary switch at the rear of the MF-IDUCTOR is
used to adjust the heating time and power. These adjustments
should be made before you press the push button on top of
the unit to activate heating. The settings can not be adjusted
during heating. Once adjustment is complete the inductor is
held around the object to be heated and the button on top of
the unit is depressed. In positions 1 to 5 the unit will switch o
automatically after the specified time. In position 6 the unit will
continue to heat until the button is released or the MF-IDUCTOR
is switched o by the internal temperature safety cut-out. Once
the MF-IDUCTOR has cooled suciently the heating process will
start up again automatically when you press the button. The MF-
IDUCTOR is active when the LED on the front is illuminated.
4.3 LED lighting and fan The LED on the front of the unit will light up to illuminate the
object when you press the button. The fan will then run to
cool the system. The fan will remain active throughout the
heating process and also thereafter if the measured internal
temperature is high. Once the temperature has returned to a
normal level the fan will switch o automatically. For this reason
the mains connection should be maintained until the fan stops
running. The MF-IDUCTOR will switch o (or fail to switch on) if
a fault is detected. In that case the LED light will flash when the
button is depressed. (See: “Error messages”.)
WARNING!
In order to prevent damage the MF-IDUCTOR
and the inductor must be allowed to cool
thoroughly after use before they are returned
to their storage box. Both the unit and the
inductors can become hot in use.

14 Schaeer Technologies
The MF-IDUCTOR is maintenance-free. The housing can be
cleaned with a dry cloth.
WARNING!
Do not use a wet cloth or solvents: these can
damage the unit or its operation. Do not use
a flexible or fixed inductor if the insulating
protective sleeve is damaged or worn.
WARNING!
The unit must always be connected to a supply
network with a fuse rated at at least 5A and at
most 16A. The unit does not have an internal
fuse. An earth bonded wall socket should
always be used on safety grounds (Class I).
WARNING!
The unit does not feature an on/o switch, as
soon as the plug is inserted in the socket the
unit will be powered up.
NOTE!
The use of a generator is permissible if it is able to deliver
adequate power and the output delivers clean sinus form
voltage in the correct frequency range (50 - 60 Hz).

NOTE!
Flexible inductors with a length of more than 2 metres
are mainly used for larger and heavier components that
require correspondingly higher power. We therefore
recommend combining these with the MF-IDUCTOR
variants with 2.0kW or 2.3kW capacity.
